I am kindly looking for an appraisal on the following components. I already have new pieces on the way, and I need to make room in my 650D Everything is in excellent used condition and has been well taken care of and cleaned regularly

You would be right if it was a regular 5870 with 1GB with a stock cooler (I see them go for around 75-80$). Not the case here, it's the Eyefinity edition which is worth more than the regular one, and it also comes with an Accelero, which has a value by itself. Can't ignore the cooler's value.
Also, from what I see, 7850 sell close to 100$ only after rebates (their original prices vary from 140 to 180$)... You may receive those rebates after a long time, or... never.
Performance wise, yeah, not exactly worth 100$, agreed.Edited by -X3- - 11/30/13 at 11:27am
